LangApp: Effortless Flashcards from Real-World Language

Overview

LangApp is a powerful command-line tool that automates flashcard creation for language learners. Feed it foreign-language text, and it will extract unknown words and pair them with precise definitions—ready for Anki import. Perfect for learners who want to grow their vocabulary from authentic sources.

How It Works

LangApp is built with robust Go code and follows a straightforward workflow:

  1. Parse a Dictionary
    Import a large multilingual JSONL dictionary (e.g., from kaikki.org) and build a local, persistent word-meaning database.

  2. Generate Flashcards
    Provide any text—LangApp identifies unfamiliar words, finds their definitions, and outputs Anki-compatible cards in cards.txt.

  3. Optimized Performance

    • Efficient, multi-threaded parsing (-t 10).
    • CLI flags for control and feedback (-p true for progress).
    • All data is stored locally for speed and offline access.

Example Workflow

1. Parse a Dictionary:

go run cmd/parser/main.go -db ./assets/meaning/ -dict ./assets/kaikki.org-dictionary-English.jsonl -t 10 -p true

Why Use LangApp?

  • Instant Vocabulary: Transform any authentic text into custom flashcards—no manual entry.
  • Anki Compatible: Output is ready for direct import into Anki for spaced repetition learning.
  • Open Source & Extensible: Free to use and customize—contributions welcome!
